CVE-2025-26343
📋 TL;DR
This vulnerability allows unauthenticated remote attackers to brute-force user PINs in Q-Free MaxTime parking management systems via crafted HTTP requests. Attackers can gain unauthorized access to system functions by guessing PINs. Organizations using Q-Free MaxTime version 2.11.0 or earlier are affected.
💻 Affected Systems
- Q-Free MaxTime
📦 What is this software?
Maxtime by Q Free
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to manipulate parking operations, access sensitive data, or disrupt critical infrastructure.
Likely Case
Unauthorized access to parking management functions, potential data theft, and manipulation of parking records.
If Mitigated
Limited impact with proper network segmentation, rate limiting, and monitoring in place.
🎯 Exploit Status
Exploitation requires sending multiple HTTP requests to brute-force PINs; no special tools needed beyond HTTP client.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 2.11.1 or later
Vendor Advisory: https://www.nozominetworks.com/labs/vulnerability-advisories-cve-2025-26343
Restart Required: No
Instructions:
1. Contact Q-Free for patch availability. 2. Apply patch to upgrade to version 2.11.1 or later. 3. Verify patch installation.
🔧 Temporary Workarounds
Implement Rate Limiting
allConfigure web server or network devices to limit PIN authentication attempts per IP address.
Network Segmentation
allRestrict access to MaxTime systems to trusted networks only using firewalls.
🧯 If You Can't Patch
- Implement strong network segmentation to isolate MaxTime systems from untrusted networks.
- Enable comprehensive logging and monitoring for brute-force attempts on authentication endpoints.
🔍 How to Verify
Check if Vulnerable:
Check MaxTime version via web interface or configuration files; if version is 2.11.0 or earlier, system is vulnerable.Check Version:
Check web interface or consult system documentation for version information.Verify Fix Applied:
Verify version is 2.11.1 or later after patch application.📡 Detection & Monitoring
Log Indicators:
- Multiple failed PIN authentication attempts from single IP address
- Unusual authentication patterns
Network Indicators:
- High volume of HTTP POST requests to authentication endpoints
- Requests with varying PIN parameters
SIEM Query:
source_ip=* AND (url_path CONTAINS "/auth" OR url_path CONTAINS "/login") AND status_code=401 COUNT BY source_ip HAVING COUNT > 10
